Title: Improvements relating to circuit breakers for direct current electric circuits
IPC: B60M3/00
Filed: 1930-05-23
Abstract: 341,831. Protective cut-out arrangements. ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Bush House, Aldwych, London.-(Assignees of Wensley, R. J. ; 111, Maple Avenue, Edgewood, Pennsylvania, U.S.A.) May 23, 1930, No. 15913. Convention date, May 27, 1929. [Class 38 (v).] To enable a high-speed circuit-breaker, connecting for example a D.C. traction feeder 11 with its bus-bars 10, to distinguish between a fault condition and a heavy load condition, there is provided in addition to the usual bucking bar 20, which shifts the flux from the holding-coil 19 away from the armature 18, a further flux-shifting coil 22 in series with a condenser 23, which normally prevents D.C. from traversing the winding 22. The reduction of voltage due to a fault in the feeder, however, causes a transient current to flow through the condenser and winding 22 so that the breaker is tripped. The reactor 21 is preferably designed to shunt a large part of the fault current from the bar 20 so that the flux-shifting is accomplished mainly by the winding 22, and in this way it can be arranged that only the breaker nearest the fault is tripped, and healthy sections are not cut out.

Title: Improvements in or relating to analog-to-digital converters
IPC: H03M1/00
Filed: 1966-04-12
Abstract: 1,147,797. Analogue-digital converters. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 12 April, 1966 [15 April, 1965], No. 15984/66. Heading G4H. An analogue-digital converter giving a binary coded output includes a capacitor resistance circuit C 2 R 3  (Fig. 6), to which is applied the unknown analogue signal, the exponentially decreasing voltage as the capacitor discharges being fed to four tunnel diodes Tu1-Tu4 in a quantization circuit Q at times t 0 , t 0  + T, t 0  + 2T ... chosen so that the voltage is halved during each interval T. If the analogue input signal has a value of five volts (Fig. 8, not shown) the first Tu1 of the tunnel diodes Tu1-4 enabled at time t 0  by a first clock pulse at terminal II changes state to apply an output pulse via diode D7 and gate S2 (enabled by a clock pulse at terminal 1 occurring simultaneously with a pulse from the circuit Q to change over a tunnel diode Tu 5 ) to a subtraction circuit M and to an output channel DA. This pulse causes a sudden withdrawal of charge from the circuit R3, C2 and hence a reduction in the voltage applied to the tunnel diodes Tu1-Tu4. On the occurrence of the next clock pulse on terminal II at time t 0  + T none of the tunnel diodes change their state (Fig. 8, not shown) and hence no output pulse is applied. On the third clock pulse at time t 0  + 2T the third tunnel diode Tu3 changes state to give an output pulse and consequently the charge on capacitor C2 is reduced to zero. The output pulses at terminal DA commence with the least significant bit. A further embodiment (Fig. 11, not shown) is described in which the output pulses depend on the state of a bi-stable device at the times T, 2T ....

Abstract: 860,891. Oil-blast switches. FABRIEK VAN ELECTRISCHE APPARATEN. May 21, 1957 [June 1, 1956], No. 16092/57. Class 38 (5). A small - oil - volume switch has a tubular insulating column 1, 2 supporting a circuitbreaking compartment or chamber 12 of lowmoulding pressure resin, the chamber housing a turbulator 7 with lateral vents 8. The turbulator is disposed so that the side containing the vents is spaced away from the wall of the chamber 12 so as to reduce back pressure. The turbulator is also mounted so as to avoid direct communication between the chamber outside the turbulator and the interior of the column to reduce oil contamination in, and the effect of shock waves on, the insulating column. In Fig. 1, porcelain insulators 1, 2 support a tank 14 in which the chamber 12 is housed. The current conductor 17 extends along the turbulator to the fixed contact 6, so that when the switch is opened the current in the conductor creates electrodynamic forces which direct the arc towards the vents 8. In a modified arrangement, the insulating column and the chamber form an integral moulding. In this case the conductor 17 is embedded in the wall of the chamber 12 and the tank 14 is omitted. Fig. 5 illustrates such an arrangement in which the conductor 17 is looped and embedded in the wall of the chamber 12.

Data transfer apparatus for the control of data transfer from a reading device adapted to sense variable length records stored serially in a source storage medium (punched paper tape) to a cyclically operable magnetic storage device (a magnetic drum) comprises switching means operable to connect the output of said reading device under the influence of control means jointly responsive to a counter synchronized with the reading device, timing means controlled by the magnetic storage device and signals derived from said reading device upon sensing an end of a record. As described, variable length records separated by beginning- of-record characters are transferred from a punched paper tape to a magnetic drum. Initially, by plug connections, a drum word length is selected. For example, a word length of 30 digits may be selected. Digits from the tape are then transferred in succession to the drum and recorded over one or more 30-digit drum word positions as is necessary until a beginning-of-record symbol is sensed from the tape, indicating the end of the record being transferred, whereupon tape reading is stopped and any partially filled drum word position is filled up with zeros. Specification 710,554 is referred to.

Abstract: 1505582 Waveguide tube LES CABLES DE LYON 18 April 1975 [25 April 1974] 16209/75 Heading F2P [Also in Division H1] A waveguide or other elongated hollow member is supported within a tubular body 5 by means of an annular filling 8, 9 made of a granular substance bound by a resinous compound which hardens at room temperature in a very short time upon contact with a gasentrained catalyst. The granular substance is preferably a neutral material such as glass powder or sand and the binder may be a phenolic resin mixed with an isocyanate. The catalyst may be an amine entrained in carbon dioxide. As shown, the waveguide comprises a conductive winding 1 surrounded by inner and outer layers 2, 4 of glass fibres and an intermediate layer 3 of woven copper gauze, these layers being bound together and to the winding 1 by a hardened synthetic resin. The waveguide is located in the vertical position within a metallic tube 5 and the annular space filled under gravity. The filling consists of alternate layers 8, 9 of granular material respectively with and without binder. The amount of binder used is such as to leave the material porous so that it may be penetrated by the catalyst. The hydrostatic pressure due to the filling is compensated by filling the interior of the waveguide with a granular material 10 having the same density as the annular filling.
